<?php declare(strict_types=1); namespace App; use Generator; use CachingIterator; $generator = /** * @return Generator<bool, bool> */ static function (): Generator { yield true => true; yield false => false; yield "foo" => 1; yield "bar" => 2; yield "baz" => 3; }; $iterator = new CachingIterator($generator()); foreach ($iterator as $k => $v) { var_dump($k, $v); } foreach ($iterator->getCache() as $k => $v) { var_dump($k, $v); }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
